Get a quoteVolume and weight: Since high frequency inverters use high-frequency switching technology and compact circuit design, their size and weight are usually much smaller than power frequency inverters. This gives high frequency inverters significant advantages in mobile power supplies, aerospace, electric vehicles, and other fields.
Switching frequency: Multilevel converters can operate at both fundamental switching frequency and high switching frequency PWM. It should be noted that lower switching frequency usually means lower switching loss and higher efficiency. Unfortunately, multilevel converters do have some disadvantages.
Due to the use of high-frequency switching technology, high-frequency inverters have the advantages of small size, lightweight, and high efficiency, but they also have the problem of relatively poor output waveform quality.
The relatively slow switching frequency of IGBTs results in higher energy losses in applications demanding rapid switching, such as high-speed motor drives. Additionally, silicon-based inverters often require bulky cooling solutions due to higher heat dissipation, which increases system size and weight.
Currently, GaN is utilized in DC/DC converters and on-board chargers, where its higher switching frequency (with high du/dt values) offers the greatest advantages. Despite these advantages, WBG-based inverters come with challenges. The higher cost of SiC and GaN devices compared to silicon counterparts remains a barrier to widespread adoption.
Multilevel inverters (MLI) have become increasingly popular in recent years for medium voltage and high-power applications. However, these devices also come with a number of other built-in disadvantages, such as a greater number of switches, a greater need for sources, and intricate control mechanisms.
